THE BASIC PROBLEMS CONNECTED WITH THE SELECTION OF LAYOUTS AND CALCULATION OF PARAMETERS OF WIND MACHINES, THEIR ENERGY-PRODUCING CHARACTERISTICS AND TECHNICAL AND ECONOMIC INDICES ARE PRESENTED. METHODS OF OPTIMAL MATCHING OF WIND ENGINES WITH WORKING MACHINES, CALCULATORS FOR STRENGTH, AND CONSTRUCTION AND AUTOMATION OF WIND MACHINES ARE ANALYZED IN DETAIL. A DESCRIPTION IS GIVEN OF THE SETUP OF DOMESTIC AND FOREIGN WIND INSTALLATIONS FOR VARIOUS PURPOSES. BASIC CHARACTERISTICS OF WIND AS A SOURCE OF ENERGY, BRIEF INFORMATION FROM AERODYNAMICS, THE THEORY OF THE WIND ENGINE AND CALCULATION OF ITS AERODYNAMIC CHARACTERISTICS ARE PRESENTED. IN CONCLUSION, RECOMMENDATIONS ARE PRESENTED FOR USE OF WIND MACHINES ACCORDING TO ZONE. THE BOOK IS INTENDED FOR ENGINEERS, DESIGNERS AND WORKERS OF SCIENTIFIC AND RESEARCH INSTITUTES CONNECTED WITH CREATION AND UTILIZATION OF WIND MACHINES AND FOR ENGINEERS AND MECHANICS IN AGRICULTURE.
